(ne object oi' -my invention is to providey a construction in connectionwith talking machines, whereby the plane of the stylus, which isperpendicular to the record and at right angles to the axis ol thereprodueer sound box, is maintained at all times substantiallytangential to the direction et' the rotation of the turn-table undconsequently to the grooves of a disk record.

A further object of my invention is to so construct the above describedmeans that it perl'orms the additional function olE taking of vibrationsl'rom both sides oi the diaphragm to produee thereby a moreexactj'reproduction oll the record.

A l'urther object, ol` my invention is to convey the sounds fromopposite sides oi the sound bo.\\Y to two independexrit arms or othersound uugmentine devices wherebyv the re.- sultiug reproduction isiouder, clearer' und more. faithful to the original sounds or tonesrecorded than hns hitherto been obtained A l'urther object ol' myinvention is to mount euch horn or other sound augmenting devices insuch a manner that it may be turned or swung at dillerent :ingles withrespect to the other in order to distribute the sounds in a manner toproduce the best and most ellective results.

A further object of my invention is to make the sound tubes, the soundbox, and the parts connected thereto of such proportions that the saidparts are suliieiently rigid to resist the tendency to vibrate in sym#pathy ith the vibrations of the air inclosed thereby, and therefore fromimparting their ownvibrations and undesirable fualities to the soundwhich is being reproduced. In other words, the parts are made so heavythat they do not partake of the vibrations of 'the air inelosed, butpermit the vibrations .from the diaphragm to be transmitted through thesame in' a, much more perfect manner than has heretofore beeneccomplished.

r Brieily, my invention consists in l revidn'ig a.' talking machine withtwo sound cnn- Speicicntion of Letters Patent.

veying tubes of heavy and rigid construetion, each of which is composedol' a rigid or ed portion secured to the side ol' a cabinet, orother-fixed part of a talking machine, and two hinged portions iree tobe swung upwardly on horizontal pivots away from the plane ol therecord, and aise to be swung about vertical pivots in a liorizontalplane over the face of the record 3 the swingin ends oi seid sound tubesbeing pivoted to 't e opposite sides oi the reproducer or sound box;

whereby the seid sound tube's are Caused to convey the vibrations ofthediaphragm from both sides of the sound box to independently movablehorns or any other sound amplifying device, and at the same timel tomaintain the sound box, and the stylus carried thereby, in a iiXedrelation with respect. tothe groove of the record as the reproducer orsound box travels across the sume.

For u full, elegir und exact description of one embodiment of myinvention, reference may be had to the accompmiying d forming a partthereol', in whichV lfigure i is a plan view of m) improved device,mounted upon e, cabinet ol' a. talking machine. Fig. 2 is u sectionalVvievv of the line L?, 2, Fig. l Fig. 3 is a section ol the line 5, I,Fig, l; Fig. fr is an elevation view of the bracket or tixed support oim y leviee.

Referring to the drawings, i() indicates the cabinet oi u talkingmachine to one side of which a bracket is rigidly Secured. The bracket(plainiy shown in Figs. i and Li) consists oi' a web 1l, terminating ina U shaped yoke l2, the upper arms oi which `are provided with elbowsi3, 1:5', forming ports of the sound conveying tubiis. The upper ends ofthe elbows are provided with shoulders, 14, 1li', and upwardlyprojecting cylindrical sleeves 15,15 which are adapted tosmoothly fitthe. smaller ends 16, 16 oi" the sound amplifying horns 17, 17. By meansof this connection between the horns and the upper ends l5, l5 oi' therigid elbows 13, 13', the horns may be independently swung around in ahorizontal lplane to form any desired angle with respect to each otherand to (listribute the sound in a much more perfect und effective mannerthan has heretofore been accomplished. The elbows 13, 13 ex tendbaekwardly for a short distance toward the center oi the talkingmachine, are then lient rs at '18,8 sind terminate in danses rau/ings byset screws,l 22,' 22. 5 rovided on its upper side with lugs 23, 23

are sleeved short tubes 20, 20.', rigidly united by crossbar 21 andsecured Iwithin the elbow Each tube 20, is

orming parts of a hinge, to which extensions 24, `221 are secured bylugs 25, and pivot 26, 26. To the other ends of the extensions 24, 24are pivoted' the tubular horizontally swinging arms 27, 27', oi thesound tubes, the connection between the said swinging arms and theextensions being clearly shown in Fig. 2, in which said extensions2li-24' are eachdprovided with a hollow, vertically dispose cylindricalportieri 28, beveled on top as at 29, while the horizontal swinging` arm27-27 each have a similar cylindrica por tion 3 0, the lower edge ofwhich is beveled to' correspond to the beveled edge 29. A

The reproducer sound box 36 (lidera from the usual cons tructionoi thesame in that both 4 .the interior cylindrical portion 37, and theveniterior v cylindrical portion 38,. are provided Withoutwardlyextending 4cylindrical sleeves 5 39 39 res actively, and withinsaidsleeves 3 1 P the connecting ,tubes Se, 3ft are lfitted. The

,connection 34 .and sleeve 39 are secured together b a bayonet slot t0,and pin el, by

' means o which thestylus 42 isquickly and accurately adjusted so thatits agus forms the propery orcorrcct angle with the face of the 20v withilanges, the outer surfaces of which are curved to conform to in arc,the center of which is in a line through the axis of the-pivots* 26, 26.The connection between the short tube 2O and the extension 24 is lainlyshown' 11i Fi 2, and is identical with t at for the short tu e 20e andthe extension 24. ln said Fig. 2, 4l re resents the iiange on the shorttube 20, an. its outci surface from the shoulder i6 to the top o'l the'flange is curved in a vertical plane to form an are of acircle'swung'fromapivot 26.`y As 'will be seen, l'have rovided theextension 24 with a correspon ing recess, within which the ilange'44'65' fits. The horizontal-pivots 26 then permit screw 3l, securelyclampssaid cylindrical positioml have provided-the short tubes 20,

conlormfto anyinequalitics or irregularities ln order-to maintain beplane of the stylus substantially tangential to 'l'hegroovel as thestylus is swung on an arc over the record, l have made the pivots ateach end of the .tubes substantially at the corners of a pan allelogram.-ln actual practice, however, I

have found that'thc distance between the i axes of the cylindricalportions 30, vshould be slightly less than that between the pivots 35,v', yconnecting the outer endol. the

3ft and by reason of this shorteningv of ons side of theparallelogram,the1axis ot thev sound box or reproducer is not maintainedat all times'- absolutely parallel to adetermined lvertical plane aswould be the case fsaid distances were eiual, but the directiongof the isaid axis is slig tly changed as the repro'- ducer travels over therecord By a careful determination of the relation ofthe Adistances,

between said pivots, the planeot'the stylus is maintained at. all timesin approximately erfect relation to the' groovesin the reco 1i addition,then, to performing the function of takin the vibrations from both sidesof the disp agm, my' sound conveying tubes also operate to so change thedirection of the airis of the sound box that the stylus is always in' aplane substantially tangential to the groove bf therecord, and as aresult of the combination of these two features in one structure the`sound 'is reproduced with greater intensity andaccuracy than hasheretoore been lossible in. ordinary forms of con struction. t will bealso A,observed that have vmade the arms, and connections of a llt veryfirm and rigid construction, and by reason of this and the manner ofsecuring them together and to the fixed parts ofthe ma chine to mutuallystrengthen and firmly hold each other, the vibrations produced b thediaphragm are not transmitted throng the material of the sound tubes,but only through. the air inclosed in the tubes. ln other words,by'making the construction-of my parts exceedingly rigid and practicallynonvibratOry, l have been enabled to limit the transmission ofvibrations yto the air inclosed in the tubes, and the vibrations are notimpartedfto or transmitted through, the connected partsyof the machine,with the result that Athe tones originally recorded upon the Irecord arereproduced with great accuracy and purity. l

f Should it for any reason be found desirable to remove the sound'box,it

bOX and maintaining the plane of; the stybox to allow the pin to beWithdrawn from the bayonet joint 40. Thus l have provided the stylus oladouble armed talking machine with thefaccurate adjustmentadorded by thebayone joint and pin heretofore employed in connection with single ermsound tubes.
